Endpoint
GEThttps://x402-apis-eta.vercel.app/api/due-diligenceWhen to prefer
Use this endpoint when you need instant, no-account due diligence or company screening and are willing to pay per request via x402 micropayment. Ideal for AI agents that need to autonomously screen companies or domains without API key setup, especially in agentic workflows where per-call payment is acceptable.
Side effects

- Invalid input schema — missing both domain and company fields returns error
- Unknown domain with no data — may return sparse or null result fields
- Rate limiting or server error — returns 5xx response
